,CLAMP-PLATE FOR RAILROAD-RAILS.

EPECIFICATION forming part of Letters Patent No. 301,668, dated J uly 8,1884.

Application filed October 26, 1883.

To all whom it may concern.-

Be it known that I, Tnioims J. BUSH, Lexington, Fayette county,Kentucky, have invented a new and Improved Clamp-Plate forRailroad-Rails, of which the following is a full, clear, andexactdescription.

This invention relates to a new form of plate for holding railroad-railsto the cross-ties, to

be used in-connection with my new locking and interlocking bolts coveredby my Patents dated May 2, 1882, and September 19, 1882, and numbered,respectively, 257,287 and 264,622.

My invention consists. first, of a plate adapted to be placed upon thecross-tie and flange of a railroad-rail, combined with interlocking-'bolts inserted in the plate and cross-tie parallel with the rail.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 shows, in sectional elevation taken on the line as :c of Fig.2, a railroad-rail secured to the cross-tie by my new plate and inter- Ilooking-bolts. Fig. 2 is a sectional elevation of the same, taken on theline y y of Fig.1. Fig. 3 is an inverted plan view of the plate, andFig. 4 is a sectional elevation showing modification of the plate.

A represents the railroad-rail, B the crosstie, G the plates placed uponthe flanges of the .rail and upon the cross-ties B, and D D rep- (Nomodel.)

ner fully described in my above-mentioned patents. The'plates G are cutaway upon the under side, as shown at d, to properly fit upon theflanges of the rail A, and they are also beveled upward upon the underside from the rear edge e to the line 0, where the cut-away portion 61begins, so that by turning nut c the plates may be clamped upon theflanges of the rail with great firmness in the first instance, and anywear taken up by turning nuts 0, as will be understood from Figs. 2 and4. The nuts 0 are made to fit firmly upon the plates 0 by beveling theplates upon the upper surfaces, as shown at ff; and in order to enablethebolts D-D to be readily inserted, the holes a a are made ellipticalin form and beveled, as shown at a, Fig. 3, and also as shown at cf,Fig. 1. Where the plates 0 are to be used on curves, they will be formedin the center with the upwardly and inwardly projecting strut O,whichis. adapted to fit under the head of the rail, as shown in Fig. 4, forbracing the rail so that it will not tip under the lateral strain oftrains passing the curve.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The plate 0, adapted to clamp the flange of therail-A upon the crosstie B, in c0mbination with the bentinterlocking-bolts D D, inserted in the plate and cross-tie parallelwith the rail, substantially as described. 2. The plate 0, formed withthe beveled holes a a, and beveled upon its upper side to form seats ffor the nuts 0 c, and cut away and beveled upon the under side andformed with or without the stud C, substantially as described.
